[Building Sakai] ClassNotfound in a tool

[Daniel Merino]

Hi everybody.

I'm trying to solve, since several days ago, a weird issue with a tool 
which launches a ClassNotFound exception, relating to a class which is 
included in the tool's WAR file.

The class not found is org.sakaiproject.util.BaseResourceProperties, 
inside sakai-kernel-util, but in the class where the exception is 
launched (org.sakaiproject.blog.impl.SakaiProxyImpl) 
BaseResourceProperties is included in the imports and the project 
compiles OK with Maven.

Also, I have looked for the lost class in the tool's deployed WAR file 
and it's included inside its kernel's WAR file.

I'm using a fresh Sakai 2.7.1 with kernel 1.1.9. The exception is 
throwed when uploading an image.

Please, could you give me some advice about what more could I try? I'm 
stuck with this.

This is what my catalina.out shows:
